CONTAINER COVER.

Application filed December 26, 1924. Serial No. 758,137.

It desirable with covers for some con tainers, particularly covers for conduitboxes to provide means which will retain the screws for securing said covers in place while the covers are put in place so that they may be readily driven to place without haudling the screws directly as such covers are often placed whereit is inconvenient to place the screws. Further on the removal of the box cover it is desirable to have the screws retained with the cover. It is further desirable to cushion the screw when itis driven to place in that such covers are usually made of porcelain or fragile material and are often cracked from screw ressure. Features and details of the inventlon will be further described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:-

Fig. 1 shows a plan View of the cover with the screws in place.

Fig. 2 a side elevation of the cover, partly in section, on the line 22 in Fig. 1, with the conduit box in dash lines indicating the position of the cover thereon,

1 marks the cover. This may be with the usual conduit openings 2.

Screw openings 3 extend through the cover and these terminate in their outer face in sockets or countersunk portions 4. Screws 5 extend through the openings, the heads extending into the sockets;

A screw retaining plate 6 is arranged in the socket, this plate having a perforation adapted to engage the screw so as to secure the same against ready displacement. The plate being ordinarily made of fibre stock yields sufiiciently to permit the forcing of the screw through it to place but yieldingly holds the screw in lace.

The plate is pre. erably made of slightly greater diameter than the socket so that it frictionally engages the outer wall and preprovided M vents the ready disengagement of the plate from the walls of the socket. To this end the plate is of sufficiently greater diameter. preferably being bent up or cupped slightly at the edges, as shown at 7 thus more securely engaging the walls of the socket, these edges being wedged or forced as it wvere by the edges of the screw against the walls of the socket. With this construction it will be seen. that the screw is yieldingly held in the opening, the head is provided with a countersink, and the retaining plate or disc not only holds the screw yieldingly in place but also forms a cushion reducing the liability of breakage when the screw set to place.

What I claim as new is z-- 1. In a container cover, the combination of a cover having an opening therethrouglr adapted to receive a securing screw said opening terminating in a socket on the outer face of the cover; and a screw retaining perforated plate in the socket, said platebeing of initially greater diameter than the socket, and said plate being of soft material with its edges cupped in engagement with the walls of the socket.

2. In a container cover, the combination of a cover having an opening therethrough adapted to receive a securing screw, said opening terminating in a socket on the outer face of the cover, a plate in the socket said plate being of initially greater diameter than the socket and having a perforation therethrough of less diameter than the screw whereby to retain the screw therein, and said plate being of soft material with its edges cupped inengagemeut with the walls of the socket.

In testimony whereof I have hereunto set my hand.

HOWARD A. SELAH.
